The PAP P20 Series Polymer Plain Bearings with Bronze Powder are high-performance components designed for industrial applications requiring durability, low friction, and self-lubrication. These bearings are constructed from a polymer material reinforced with bronze powder, which enhances their strength, wear resistance, and load-bearing capacity. Below is a detailed overview of their features, applications, and specifications:
Key Features
Material Composition:
The bearings are made of steel + bronze powder + POM (Polyoxymethylene). The bronze powder reinforcement improves strength and wear resistance, while the POM layer provides self-lubricating properties179.
Self-Lubricating:
The POM material ensures the bearings operate without the need for external lubrication, reducing maintenance requirements and downtime19.
Durability and Wear Resistance:
The bronze powder enhances the material's ability to withstand high loads and speeds, making it suitable for demanding industrial environments17.
Customizable Sizes:
The bearings are available in a wide range of standard and customized sizes, ensuring compatibility with various machinery and equipment179.
Low Friction and Smooth Operation:
The plain bearing design ensures low friction and efficient power transmission, contributing to smooth operation16.
